Were my reasons for breaking up with my boyfriend fair?

My ex boyfriend and I dated for 7 months before getting into a relationship and 6 months before we broke up. He was never really my type but I thought I should try something new because he was really attentive, giving, and nice, and he took me to his hometown to meet his mom and sister. The problem is I caught him in a lie twice involving other females. I also made a fake fb page and pretended to be a girl who was interested in him; he reciprocated the interest and we were bf and gf at this time. When he got caught he claimed he knew it was me the whole time. When went to the club together once and he slow danced (grinded on) the same girl for 3 songs straight. When I addressed the girl she told me he had been talking to her and trying to pursue her. I tried to break up with him after this but he sobbed and sobbed saying that he loved me too much to cheat on me, that the girl was drunk that night and she was liar. Additionally, his sex drive is extreme. He masturbates EVERYDAY faithfully, he seems insatiable, talks about sex constantly and my sex drive doesn't match his. He told me he could handle it because he loved me so sex didn't matter, he would just continue to masturbate. I felt that I should break up with him because I can't trust him and my intuition tells me that he is secretly really sneaky. I asked my roommate for advice and she says that he is a great guy and that I am merely looking for reasons to break up with him. Now I feel guilty because maybe I did just let a great guy go. I feel like an attentive bf, who is giving, has a great future ahead of him and has a great sex drive is every girls dream and maybe I made a mistake. What do you guys think? HELP please.
